Abstract
A storage system determines whether its memory is fragmented (e.g., based on a host read pattern that indicates that a sequential file is being read, but the number of data sense operations required to perform this read indicates that file is stored non-sequentially in the memory). If the storage system determines that its memory is fragmented, the storage system can perform a defragmentation operation on the memory. This defragmentation operation can be done invisibly to the host (i.e., without receiving any hint or instruction from the host to perform the defragmentation operation).
